KEY-HOLE GUARD.

' SPECIFICATION forming part of Letters Patent No. 285,074, dated September 18, 1883,

Application filed J une 6, 1883. (No model.)

' To all whom it may concern:

Be it known that we, LYMAN RIIoAnEs and JOHN PHILIP SIPP, both citizens of the United States, and residing in the city, county, and State of New York, have invented a new and useful Key-Hole Guard, of which the following is a specification.

Our invention relates to an improvement in key-hole guards; and the objects of our iniprovement are to protect the key-holes of any of the well-known shapes, so that the locks cannot be locked or unlocked with their proper key 5 to do this without altering the lock in any way, or even unlocking it, and with little expense. We attain these objects by the mechanism illustrated in the accompanying drawings, in whicl1- Figure 1 represents the front of a lock,showing a key-hole to be guarded. Fig. 2 represents the same with our invention applied to it. Fig. 3 represents a sectional view of the same, showing part of the interior of the lock and our invention applied to it. Fig. 4 represents the two parts of the fastener; Fig. 5, a padlock for securing the parts in position,and Fig. 6 the key of the same.

Similar lettersrefer to similar parts throughout the several views. p

a is a hook to be inserted in the key-hole; s, an eye-hole in the handle of a; Z), a blank key to be inserted in the key-hole after a is inserted; it, an eye-hole in the handle of b,-

c, an ordinary small padlock, for the purpose hereinafter described; (I, the key of c; e, that part of the face of the lock which turns with the key 5 f, that part of the key-hole which re mains stationary.

In locks which have a keyhole similar to the one represented in the drawings our invention may be operated, as shown. The hook to is inserted into the key-hole in the part 6 of the face of the lock, and e is turned with it until the hook proper of a comes under the face of the lock and is caught in the lock, leaving the part of the key-hole marked f open. b is then inserted in f. The handles of a and b are brought together, when the eye-holes s and i will be alongside of each other. -The hook proper of a comes against 12, and a cannot be drawn out until Z) is first removed. The two are then fastened together, which may be accomplished, as shown in the drawings, by passing the hasp of a padlock through the eye-holes in their handles and padlocking them together. The handles of a and I) should be slightly bent.

To use our invention on locks in which all the key-hole turns with the key, there being no stationary part f, or in which all the keyhole is stationary, the shank of a is best made round. a is inserted and turned in the keyhole. I) is then inserted, and our invention operated as described. For small key-holes of this kind the shank of a may be made of strong wire and have the hook proper soldered toit. j

The size of a and b may be regulated according to the key-holes in which they are to be inserted. V

The drawings represent a lock with a hub to it; but our invention may be used in the same manner when the key-hole is in the face of the lock.

Our invention may be alsooperated in locks having narrow slits for key-holes by inserting the hook in the key-hole and moving it up pr down, according to the way the hook is inserted, until the hook is caught under the face of the lock or in the lock, then inserting the blank key behind it, so that the hook cannot be removed until the blank key is first drawn out and fastening the two together.

The shanks of a and b are made long, so that they may be used in any keyhole.

Having described our invention, what we desire to secure by Letters Patent is- 1. In the hereinbefore-described key-hole guard, the combination of the piece a, having a hook at its inner end or the end to be inserted in the key-hole, and an eye-hole at its outer end, and the straight piece I), having an eye-hole at its outer end, substantially as and for the purposes described;

2. In the hereinbefore-described keyhole guard, the combination of the piece a, having a hook at its inner end and an eye-hole at its outer end, and the straight piece I), having an eye-hole at-its outer end, and the padlock a, substantially as .and for the purposes described.
